  "details": "WeGIA is a web manager for charitable institutions. In versions prior to 3.7.3, when a user logs in, html/login.php hashes the submitted password using PHP's hash() function with the SHA-256 algorithm and no salt before comparing it to the stored value. The password change flow in controle/FuncionarioControle.php follows the same pattern. SHA-256 is a general-purpose cryptographic hash built for speed, not password storage. Without a salt, identical passwords produce identical digests, making the entire hash database vulnerable to a single precomputed rainbow table lookup. This vulnerability is fixed in 3.7.3.",
